-      Texinfo is the official documentation format of the GNU project.
-      It was invented by Richard Stallman and Bob Chassell many years
-      ago, loosely based on Brian Reid's Scribe and other formatting
-      languages of the time.  It is used by many non-GNU projects as
-      well.
-
-      Texinfo uses a single source file to produce output in a number
-      of formats, both online and printed (dvi, html, info, pdf, xml,
-      etc.).  This means that instead of writing different documents
-      for online information and another for a printed manual, you
-      need write only one document.  And when the work is revised, you
-      need revise only that one document.  The Texinfo system is
-      well-integrated with GNU Emacs.
